I am new to using C# and componentSpace for SAML2 and have been tasked with debugging someone elses code. I have come across this error when trying to access the site through SAML2 and dont know what to do exactly:

This usually means that the ComponentSpace.SAML2 DLL used to build the application is different from the version available at runtime. For example, if you built your application against v2.6.0.17 of the SAML2 DLL but at runtime v2.6.0.16 is available, you’ll get an error. Please ensure that you build and publish your application including the SAML2 DLL. This means a copy of the SAML2 DLL will be included in your application’s bin folder. Also make sure that the SAML2 DLL hasn’t been published to the GAC on the target server.

If I use the nuget from Visual Studio 2.0.5 version would this be compatible with the 2.6.0.17 version that they are currently using?
The ComponentSpace.Saml2 package at https://www.nuget.org/packages/ComponentSpace.Saml2/ is a .NET Standard 2.0 library for ASP.NET Core. It’s not the same as the v2.6.0.17 and later that target ASP.NET rather than ASP.NET Core. The installer for the SAML v2.0 for ASP.NET includes the NuGet packages in the Bin folders. You can configure a local NuGet package source in Visual Studio NuGet Package Manager to reference the local Bin folder containing the NuGet package.
